I liked the idea, but it doesn't seem to work for me on my Macbook Pro 15 2017.
I had to open it twice for it to show me the instructions to activate it in the accessibility menu, and after that when I open it, it doesn't do anything.

@cataplines@aletocar@kees_romkes Hi guys, I find a issue when Separate Spaces disabled, can you enable this setting and try again ( System Preferences -> Mission Control -> ☑️ Displays have separate Spaces ) , I will release a new version to fix it later. Thanks.
